VIMPROVEMENT IN CORN` AND PEA PLANTERS.

' Specification forming part of Letters Patent No. 219,482, datedSeptember 9, 1879; application iiled July l2, 1879.

.soN and ROBERT FREDERICK JOHNSON, of

Brownsville, in thel county ot' Haywood and Stateoi' Tennessee, haveinvented a new and Improved Oorn `and Pea Planter; and we do herebydeclare that the followin g is a full, clear, and exact description ofthe same.

Our invention is an improvement in the class of seed-dropping machineswhich have reciprocating seed-slides that are operated by the rotationof the transporting-wheels, or the axle on which they are mounted.

The invention relates to the construction of the seed-slides and adjacent parts or devices which co-operatc therewith, as hereinafterdescribed.

In the accompanying drawi11gs,tbr1'nin g part of this specilication,Figure l is a longitudi nal section of the machine on line .r x, Fig. 2.Fig. 2 is a plan View of the same, the hopper being` detached. Fig. 3 isa detail enlarged section on line yy, Fig. l. Fig. 4 is a plan view ofone of the seed-slides detached. Fig.

` 5 is a cross-section of one of the seed-slides and pushers.

The frame A oi' the machine is mounted on the axle B or"transporting-wheels O, and provided with the usual attachments of'furrow`opeiier D and hinged coverer E.

in the cavity oi' each slide, as shown in Fig. l.

The seed enters the cavity c as each slide moves forward beneath thehopper, and when it moves back the pusher H forces it into the openingor eye b, from which it falls into the spout I,.when the slide againmoves forward and passes beneath the cut-oit' brush K. Thus each slidereceives a certain quantity or charge in its cavity a at the same timethat the pre! vious charge is being delivered from its eye b. Thereception of the seed into the slide-cavity and the action of theejector or pusher H insure a uniform regular discharge ot seed, whateverbe the quantity or consequent pressure of seed in the hopper G, and alsoirrespective of the violent motion ofthe machine in passing over roughground.

The under side of each slide is provided with a lengthwise groove, c,Fig. 1, at the front end. to receive a pin, d, iixed in the plate L,which supports the slides. The pin is located contiguous to the openingc in the said plate, and inclines toward or over the latter,

so that it clears the seed from the slide-eye 1),'

and prevents clogging or obstruction of the same.

The slides F reciprocate simultaneously, but in opposite directions.Theirforward move- 'ment is caused by the action on their rounded endsof the cams, or wipers M. that project from the axle B, and theirbackward movement is due to the traction of cords N, that connect therespective slides with the centrally-pivoted lever O, which is locatedon the rear portion of the- 'rame A in the plane of' the slides F.

When a wiper, M, strikes the rear end of one slide F and forces itforward, the cord N, attached to it, turns the lever O on its pivot, andthereby draws the other slide back a correspondingdistance; and when theslide which has been thus retracted is, in turn, forced forward by itswiper M, the other slide is similarly retracted or drawn back, and sothe slides continue to reciprocate in opposite directions, and toalternately discharge a determinate quantity of seed. This operation ofthe slides is effected with lessfriction and a less expenditure of forcethan in machines in which their action depends in part upon springs.

Onecompartment of the hopper may contain corn, and the other pease orbeans.

In some cases we may wish to cut od' the discharge of seed from onecompartment of the hopper G, and to .this end wel make the lowerportion, P, of its partition movable, so that it can be lowered to ahorizontal position to cover one ofthe seed-slides, as shown in dottedlines, Fig. 3. The movable section P is hinged at its lower edge, andwhen it is designed to allow both hopper-compartments to discharge seedit is held vertical by the hook R, as shown in full lines, Fig. 3.

What we claim is- 1. In n seed-droppcr, the combination of the tixedpusher With the reciprocating'seed-slide, having,` in its upper side aylengthwise recess or cavity extending back from the opening` throughwhich the seed is discharged, said pusher being` of less length thanthewztvity, but fitting therein, as shown and described, to operate asand for thi'l purpose specified.

2. In e seed-dropl'iing,` machine, the combination ofxed pins with theslides having a groove in the under side leading1 to thedischarge-openin g thereof, substantially as shown and described, forthe purpose specified.v

3. In it seed-dropping machine, the hinged or movable partition, incombination with the hopper und its two contiguous seed-slides,substantielly ns shown and described,fcr thepurpose specified.
